From the Courthouse Square to the Master-Planned Communities

Richmond is the Fort Bend County seat, and the blocks around the 1908 county courthouse hold some of the oldest homes in the county. Those houses tend to have short attics, small duct runs and rooms added on long after the original system went in, so one end of the house can run several degrees off from the other.

Most of Richmond's growth is in the master-planned communities that have filled in around the old town, such as Pecan Grove, Long Meadow Farms, Harvest Green and Aliana. Many of those homes are two stories, often with a second system or an attic air handler serving the upstairs. Upstairs bedrooms that stay warm long after the thermostat is satisfied are a familiar complaint, and the cause can be in the ductwork, in how the system was sized, or in a room that would be better served by its own ductless mini-split.

Common AC and Heating Problems in Richmond Homes

Long, humid summers and quick winter cold snaps are hard on equipment. These are the problems behind most calls for AC and heating repair in Richmond:

  • AC running but not cooling: low refrigerant from a leak, a dirty evaporator or condenser coil, or a failed capacitor.
  • Frozen indoor coil: usually restricted airflow from a clogged filter or a blower problem, sometimes low refrigerant.
  • Water dripping from the attic: a clogged condensate line or overflowing drain pan under an attic air handler, which can stain or damage the ceiling below.
  • A hot second floor: airflow, duct or sizing problems that leave upstairs rooms behind the rest of the house.
  • No heat on the first cold night: a furnace igniter or pilot problem, a heat pump stuck in defrost, or failed backup heat strips.
  • A system that never shuts off: an undersized or aging unit, a refrigerant leak or a thermostat that has lost its calibration.

Our HVAC Services in Richmond

AC Repair and Tune-Ups

When the air conditioning stops keeping up in a Richmond summer, our technicians troubleshoot the whole system to find the real cause, not just the symptom. Our AC repair service covers all types of air conditioners, and our tune-ups include cleaning and inspection to keep your system running at its peak efficiency.

Air Conditioner Installation

When an older system isn't worth another repair, we help you choose the right air conditioner and make sure it's sized and installed correctly. Our AC installation options include Armstrong Air systems up to 23 SEER, with a detailed quote before any work begins.

Furnace and Heat Pump Repair

Richmond winters are mild most of the time, which means a heating problem often goes unnoticed until the first real freeze. We provide heating repair for gas and electric furnaces, heat pump repair for systems that won't heat or keep icing over, and repairs for ductless systems in heating mode.

New Furnaces and Heat Pumps

For replacements we install Armstrong Air furnaces, from 80% AFUE models to a 96% AFUE variable-speed furnace, and Armstrong Air heat pumps that handle both heating and cooling with a single system.

Ductless Mini-Splits

A mini-split adds heating and cooling to a room without new ductwork, which makes it a practical fix for a hot upstairs bedroom, a game room over the garage, a converted garage or an addition. We install Mitsubishi ductless systems, including multi-zone models that run from 2 to 8 indoor units, and we handle mini-split repair and maintenance.

Indoor Air Quality and Humidity Control

Gulf Coast humidity doesn't stop at the front door. Our indoor air quality services include Aprilaire dehumidifiers, air cleaners, UV air purifiers and ventilation systems.

Commercial HVAC

We also install, maintain and repair rooftop units, unit heaters and split systems for commercial HVAC customers in Richmond.

Filters and Maintenance

Two visits a year through our maintenance agreement catch small problems early, and our Filter Shop ships air filters directly to your door between visits.

Richmond Heating and Cooling FAQ

Yes. Third Coast Air & Heat repairs furnaces, heat pumps, air conditioners and ductless mini-splits for Richmond homes and businesses. Our certified technicians are based in Needville, and Richmond sits well inside the area we serve, 50 miles around Houston. Call (281) 638-2175 to book a repair or a tune-up.

Yes. A new heating and cooling system is an investment, so Third Coast Air & Heat offers financing for qualified applicants. That covers new Armstrong Air furnaces, heat pumps and air conditioners as well as Mitsubishi ductless mini-splits. Ask about financing when you schedule your estimate at (281) 638-2175.

Usually not if the repair involves refrigerant. R-22 is no longer produced, so recharging an older system keeps getting harder, while new systems use lower-GWP refrigerants such as R-454B. A minor electrical or part repair can still make sense, and we'll explain the differences between repairing and replacing so you can make an informed decision.

Often, yes. A furnace and air conditioner share the indoor blower and ductwork, so replacing both at once lets us size and match them as one system, and we offer full system design with Armstrong Air equipment. If one of the two is much newer, replacing only the older unit can make more sense.

Warm air from the vents, weak airflow, a system that runs constantly or keeps cycling on and off, ice on the refrigerant lines, water leaking indoors, new noises and rising energy bills all point to a problem. Calling at the first sign usually means a smaller repair, and our technicians will troubleshoot the cause.
